Vitamin D · Common deficiency, overstated cure-all
Test, correct if low, and ignore the megadose marketing.
Revisado médicamente por Bernard Garcia, MD
Qué es
Vitamin D deficiency is common, especially with limited sun exposure, darker skin or obesity, and correcting it matters for bone health. Large trials of supplementation in people who are not deficient (VITAL and others) found no benefit for cancer, cardiovascular disease or most other outcomes.
Cómo funciona
Vitamin D is made in skin and obtained from few foods; a 25-OH vitamin D blood test measures status. High-dose injections ("D3 shots") are used in some clinics; oral supplementation is the standard and toxicity from megadoses is real.

Preguntas frecuentes
Should everyone take vitamin D?

It is sold alongside peptides and hormones as "longevity" — and it is one of the few things here that a simple test settles.
